How single-member districts are reinforcing local independents and strengthening mayors: on the electoral reform in Polish local government

Abstract

ABSTRACTIn this article, we investigate whether the design of the electoral system used in the elections of local councils affects the position of national parties and their main competitors, local independent lists. We study the case of the electoral reform enacted recently in Poland which modified the rules of council elections by introducing the first-past-the-post (FPTP) system, quite rarely used in local elections. Using empirical evidence from the municipalities where FPTP replaced the open-list proportional representation (OLPR) system, we demonstrate that the introduction of single-member districts, and majoritarian rule in council elections, increased the number of single independents, unaffiliated to any party or committee, and limited the (already poor) presence of party candidates and councillors. The reform also strengthened the position of directly elected mayors, in Poland – usually independent, by assuring many of them safe majorities in councils. We found that the share of seats for the winning mayor’s list increased by 10 pp on average after the reform.
